Subject: Re: Segmentation Faults with both 062608 snapshots

More on my segmentation problems. Just looking at the end of each kernel
message, they always end with:
EIP [XXXXX]  jbd2_journal_data_metadata-XXX

This occurs when I try to copy data from my main partition to a backup
partition or make a tarball.

Both partitions are setup with flex_bg,meta_bg,uninit_bg with ordered data
mode using noatime,nodiratime,journal_async_commit mount parameters.

Again, the snapshot from 062508/0019hrs GMT --
ext4-patch-queue-b5db22ef52ed53d8e3fa978a5a29e1609c9333aa.tar.gz
works fine patching a clean linux-2.6.26-rc6 source and exhibits no
problems whatsoever.

Starting with the next snapshot (062608/0042hrs GMT) is where my segfaults
start. This continues using the newest snapshot from 062608/2251hrs GMT.

I have patched the source from the individual snapshots mentioned as well
as just pulling and updating my ext4-patch-queue folder with the same
results. If I roll the kernel back to the 062508/0019 snapshot, the
problems vanish.

No errors noted during e2fsck -fvy on either partition.

This is driving me crazy!

Gary
